An assembling operation of a wiper motor is facilitated. An output shaft and a gear shaft of the sector gear part are connected by a swinging plate. A first slidable contact member is mounted on a tip of the output shaft, and a second slidable contact part is mounted on a tip of the gear shaft. Since these slidably contact with a cover, axial-directional movement of the respective shafts is restricted. In addition, a provisional holding part having a leg part extending in an axial direction and a claw part protruding from the leg part is formed integrally with the second slidable contact part, and the sector gear part and the swinging part are sandwiched between the claw part and the second slidable contact part, whereby the motive power conversion member and the swinging plate are provisionally held.

Wiper motor

By reducing thickness of a slidable contact member which is attached to an output shaft and a sector gear part and slidably contacts with a gear case, a wiper motor is downsized. A motive power conversion member comprises: an arm part rotatably connected to the worm wheel; and a sector gear part meshing with the output gear, wherein a gear shaft of the sector gear part is swingably supported with respect to the output shaft by a swinging plate. A first slidable contact member is mounted on a tip of the output shaft, and a second slidable contact part which is formed separately from the first slidable contact member is attached to a tip of the gear shaft, wherein the first slidable contact member and the second slidable contact part slidably contact with a cover of the gear case.
